hi thanks, don't have a pic with me right now. the circuit breaker link is :
https://www.amazon.ca/Trac-Outdoor-T10171-Digital-Circuit/dp/B00MXYCU1S. unit can be turned on/off, and has options for amps from 30 to 60.
there are 3 connection points, BATT, LOAD and pre wired ground wire on this breaker.
my plan was to use this between my 200 watts of solar on my RV and MPPT Renogy combo DCtoDC MPPT, but wanted to test it first to see if it all worked before hooking it all up.
im using a Renogy DC to DC with charge controller.
i tried a 40 watt panel i have to test it out. i have BATT side to the panel + wire, panel - to ground, Load to the input + on the Charge controller and pre- wired ground to a common ground busbar.
as soon as i hook up the panel the circuit breaker just quickly flashes on off like its breaking and resetting really fast. I've never used one of these before but thought it would be an upgrade to the regular manual reset type of breakers I've used in the past.
i connected my 40 watt panel to the charge controller briefly without a breaker just to see if it was something up with the panel or if it was the breaker. direct connect to controller seemed to work as solar light came on. all i changed was taking the + solar wire direct to MPPT input instead of to the BATT on the circuit breaker.
i have a second one of these that i substituted in to check if i got a bad one and it seemed to work for about 5 seconds and then started tripping and resetting like the other one, maybe these thing are just not meant for this type of application?
So i wanted to make sure when you have a breaker/fuse between the panel and controller that BATT side would be to the panel and LOAD side to charge controller? i think with this unit it makes a difference.
